Visual LISP, AutoLISP and General Customization

[#1]

Hi!

I´m looking for oportunities to can modify a polyline with 4 or more segments in a polyline with arc. I think it´s possible to pick start and end segment first and than all straight segements to will be in arc segments. Have you a idea to can do this.

[#2]

Hi,

I'm not able to imagine what you want to do, e.g how should this polyline with 4 segments be converted to one arc?

Prepare some samples so we can see the rules you'd like to follow.

Have a look, in example you can see a polyline with 5 segments. Maybe Autocad have a function which I don´t know to modify segement 2,3,4 in arc-entities so all arc goes tagential in together. It´s a little complicate as use fillet only and I don´t realy like to use pedit to confirm in a curve, better is a polyline with line and arc.

Hi,

if you would like a progi that automatically finds that situations where an arc may fit .... it's not the easiest job with a lot of intelligence within the app.

If you want to get this result with support by the user you can:

• draw a circle with tangent to first curve, tan to last curve and a point to pass through (in your sketch point 3)
• start _TRIM and trim the "inner side" of the circle and the polyline-segments
• connect the resulting objects using _PEDIT.

Yes I done it before but I was asking if there another solution maybe with lisp. I need thinking little...

Is it possible to erase segments from polyline

[#7]

Hi,

>> Is it possible to erase segments from polyline

I would do a _BREAK and show the points (start- and endpoint of the segment(s)).

Without development there is no command or function available for "erase segment of polyline".
